How to Share Ethernet via Wi-Fi on macOS 13

Yes, you can easily share your Mac’s wired Ethernet connection as a Wi-Fi hotspot in macOS 13 (Ventura). This built-in feature, called Internet Sharing, allows your Mac to act as a wireless router for your smartphones, tablets, and other computers. Below is a quick, step-by-step guide to configuring and securing your personal Wi-Fi hotspot using the macOS Ventura System Settings.

Prerequisites

  • An active, working Ethernet internet connection connected to your Mac (via built-in Ethernet, a dock, or a USB-C adapter).
  • Wi-Fi turned on, but not connected to an existing Wi-Fi network.

Step-by-Step Setup

  1. Open System Settings: Click the Apple menu () in the top-left corner of your screen and select System Settings.
  2. Navigate to Sharing: In the left sidebar, click General, then click Sharing on the right side.
  3. Open Internet Sharing Options: Scroll down to find Internet Sharing. Do not toggle the switch yet. Instead, click the small Info (i) icon located to the right of the toggle.
  4. Select Connection Source: In the Share your connection from dropdown menu, select your wired connection (e.g., Ethernet, USB 10/100/1000 LAN, or your adapter's name).
  5. Select Output Method: In the To devices using list below, check the box next to Wi-Fi.
  6. Configure Hotspot Security: Click the Wi-Fi Options… button at the bottom:
    • Network Name: Enter a name (SSID) for your Wi-Fi network.
    • Channel: Leave this on default unless you experience interference.
    • Security: Change this from None to WPA2/WPA3 Personal or WPA2 Personal.
    • Password: Enter a secure password and verify it.
    • Click OK to save the network settings.
  7. Enable Internet Sharing: Click Done to exit the configuration sheet, then switch the toggle next to Internet Sharing to the On position.
  8. Confirm: If prompted to confirm starting the network, click Start.

Once enabled, the Wi-Fi icon in your Mac's menu bar will change to an icon showing an arrow inside a Wi-Fi symbol, indicating that your Mac is actively broadcasting an internet connection. Other devices can now search for your network name and connect using the password you set.
